Having said that, a quick glance at the web site here does go into detail about the devices used to produce the 'random' numbers. The only bit I might question about that is: "They are subjected to calibration procedures based on large samples, typically a million or more trials, each the sum of 200 bits." Whilst this might sound good for the validity of the experiment it is inherently limiting the kind of data they output in the long term, hmmmm.Athan said:I've not bothered to read the specific article linked but did read another on the same subject. It made absolutely no mention of exactly, or heck, even vaguely, how they were generating the random numbers. The usual PRNG? How often, if at all, was it reseeded ? Or are they actually using some source of entropy? If so is there any way that source could have been influenced ?
Chilly said:Oh and Tom - nuclear decay is probably the most random thing we as humans can observe.
OMG, you're channeling Einstein!nath said:But does that mean it's actually random? Surely ultimately everything that happens has a reason, and as such it's not really *random*.
Coin tossing is actually a bad example when talking about random events.nath said:Surely predictability is based around how much we, as observers, know. As such flipping a coin 100 times looks random but if we actually take in to account *every* factor governing it, from the muscles in the hand to the climate to the state of mind of the *ahem* tosser.
If you know absolutely every factor governing the toss, surely it's no longer random, it's actually entirely predictable. The question is, can't you apply this thought process to everything that we think is random?
Athan said:With Quantum Mechanics in play there ARE truly random events, things just become probabilistic.
It's in practice too, at least in some situations.dysfunction said:In theory...
Just because the so called "randomness" can't be explained/measured/whetever doesnt mean its random...

Athan said:Google for 'Uncertainty Principle'. To summarise/precis, you can never know the exact position of a particle AND it's exact current velocity. This is NOT a limitation in measuring methods but a fundamental Universal "you cannot do that" thing.
We'll just have to agree to disagree on that one I think. Especially as it's starting to get somewhat existential.nath said:My point was not so much that we, as members of this universe, can know everything that will happen, but that random events aren't possible as there's always a reason. Sure, effectively they're random since there are things that we can never know, so they may aswell be - but ultimately there's always a reason for stuff happening.
Go on then....Catsby said:Catsby notes that having no definition of random may be misleading this thread.
